(LU930/LU930D/LH930/LH930D)
Shifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the projector to be
positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image height or width. You can turn the
knobs on the projector to shift the projection lens in any direction within the allowable range depending
on your desired image position.

To reach the highest or lowest projection position:
1. Turn (Up/Down).
2. When you feel it is reaching the limit, turn
(Left/Right) to the left or right and turn
again.
3. Repeat the step above until finding the suitable position you need.
• If you hear a "clicking sound" during the adjustment, it means that the knob is past its adjustment limit. Please
stop adjusting it, in order to avoid any unexpected damage, and turn the knob in the opposite direction, at least
to one step before the click.
• If you can't turn it back, please press and turn the knob back at same time.
